Common Causes and Solutions:

• Check your Shopify Payments settings:
  • Verify that Shopify Payments is activated in your Shopify admin under Settings > Payments.
  • Ensure you haven't accidentally enabled test mode, which would block real transactions.
• Review your Payment Gateway Configuration:
  • If you're using a third-party payment gateway, double-check that you've entered the correct credentials (API keys, passwords) in your Shopify settings.
  • Make sure your payment gateway account is active and in good standing.
• Test your payment gateway:
  • Shopify offers a test mode for most payment gateways. Use the Shopify Bogus Gateway or enable test mode in your third-party gateway settings to simulate a transaction and identify any errors.
  • The payments of vally plant training is working.
